[jquery] Filtering Table rows using Jquery

I found a Jquery script that does the table filtering stuff based on input field. This script basically takes the filter, splits each word and filters table rows with each word. So at the end you'll have a list of rows that have all the words in the input field.

http://www.marceble.com/2010/02/simple-jquery-table-row-filter/

var data = this.value.split(" ");

$.each(data, function(i, v){
     jo = jo.filter("*:contains('"+v+"')");
});

Now, what I need is that instead of filtering rows that contains each of the words in the input field. I want to filter all the rows that contain at least one of the word in the input field.

One way I've tried is to take each filtered lists into an array...

  var rows = new Array();

 $.each(data, function(i, v){
     rows[i] = jo.filter("*:contains('"+v+"')");
 });

At this stage, I have to make a UNION of all the rows in "rows" array and show them. I'm lost on how to do that exactly.

Above script in action - http://marceble.com/2010/jqueryfilter/index.html?TB_iframe=true&width=720&height=540

If I type "cat six" in the filter, I want to show three rows.

I used Beetroot-Betroot's solution, but instead of using contains, I used containsNC, which makes it case insensitive.

$.extend($.expr[":"], {
"containsNC": function(elem, i, match, array) {
return (elem.textContent || elem.innerText ||
"").toLowerCase().indexOf((match[3] || "").toLowerCase()) >= 0;
}
});

There's no need to build an array. You can address the DOM directly.

Try :

rows.hide();
$.each(data, function(i, v){
    rows.filter(":contains('" + v + "')").show();
});

EDIT

To discover the qualifying rows without displaying them immediately, then pass them to a function :

$("#searchInput").keyup(function() {
    var rows = $("#fbody").find("tr").hide();
    var data = this.value.split(" ");
    var _rows = $();//an empty jQuery collection
    $.each(data, function(i, v) {
        _rows.add(rows.filter(":contains('" + v + "')");
    });
    myFunction(_rows);
});

UPDATED DEMO

i have a very simple function:

function busca(busca){
    $("#listagem tr:not(contains('"+busca+"'))").css("display", "none");
    $("#listagem tr:contains('"+busca+"')").css("display", "");
}

nrodic has an amazing answer, and I just wanted to give a small update to let you know that with a small extra function you can extend the contains methid to be case insenstive:

$.expr[":"].contains = $.expr.createPseudo(function(arg) {
    return function( elem ) {
        return $(elem).text().toUpperCase().indexOf(arg.toUpperCase()) >= 0;
    };
});

Adding one more approach :

value = $(this).val().toLowerCase();
$("#product-search-result tr").filter(function () {
$(this).toggle($(this).text().toLowerCase().indexOf(value) > -1)
});

based on @CanalDoMestre's answer. I added support for the blank filter case, fixed a typo and prevented hiding the rows so I can still see the column headers.

    $("#filterby").on('keyup', function() {
        if (this.value.length < 1) {
            $("#list tr").css("display", "");
        } else {
            $("#list tbody tr:not(:contains('"+this.value+"'))").css("display", "none");
            $("#list tbody tr:contains('"+this.value+"')").css("display", "");
        }
    });

tr:not(:contains(.... work for me

function busca(busca){
    $("#listagem tr:not(:contains('"+busca+"'))").css("display", "none");
    $("#listagem tr:contains('"+busca+"')").css("display", "");
}

I chose @nrodic's answer (thanks, by the way), but it has several drawbacks:

1) If you have rows containing "cat", "dog", "mouse", "cat dog", "cat dog mouse" (each on separate row), then when you search explicitly for "cat dog mouse", you'll be displayed "cat", "dog", "mouse", "cat dog", "cat dog mouse" rows.

2) .toLowerCase() was not implemented, that is, when you enter lower case string, rows with matching upper case text will not be showed.

So I came up with a fork of @nrodic's code, where

var data = this.value; //plain text, not an array

and

jo.filter(function (i, v) {
    var $t = $(this);
    var stringsFromRowNodes = $t.children("td:nth-child(n)")
    .text().toLowerCase();
    var searchText = data.toLowerCase();
    if (stringsFromRowNodes.contains(searchText)) {
        return true;
        }
    return false;
})
//show the rows that match.
.show();
